This is the best flourless chocolate cake recipe ever. It is a rich, intensely chocolatey, gluten-free dessert made with only 7 ingredients! It's a delicious & elegant make-ahead treat for any special occasion.
Preheat oven to 300 degrees F. Grease one 9” round cake pan (or glass pie plate) and set aside. (Note: I always cut a piece of parchment paper into a circle with “handles” and place it on the bottom of the pan. Then I grease the pan with the parchment paper in it).
In a small saucepan over medium heat combine the water, salt and sugar. Whisk every 60 seconds until completely dissolved and set aside.
Melt the chocolate chips (in the microwave or in a double boiler) and pour into the bowl of a standing mixer.
Cut the butter into 1 Tablespoon pieces and beat it into the chocolate, 1 piece at a time.
Mix in the warm sugar/water mixture until combined.
Slowly beat in the eggs, one at a time until completely smooth.
Add vanilla and mix until just combined.
Pour the batter into the prepared pan.
Prepare the water bath
Put the 9" cake pan in a larger pan then put the pans in the preheated oven.
Once in the oven, pour boiling water into the larger, bottom cake pan until it reaches halfway up the sides of the 9" cake pan that contains the flourless chocolate cake.
Bake
Bake the flourless chocolate cake in the water bath at 300 degrees F for 45 minutes. The center will still look a little wet, but the edge will look set and the cake should only jiggle slightly.
Remove the cake from the water bath and let it cool on a wire rack.
Chill overnight
Chill cake overnight (or for at least 6 hours) in the pan.
Serve
Carefully lift the parchment paper out of the pan and the cake with it. Put it on a serving plate and sprinkle with powdered sugar! Serve with fresh berries, ice cream, etc!

Notes
*Nutritional information calculated based on the recipe yielding 12 servings, although it is very rich and I find it can definitely serve more!
Note about pan size:
The size of the pan used will effect baking times:
9" cake pan - bake for 45 minutes.
8" cake pan (must be 3" deep) - bake for 50 minutes
Individual ramekins - bake 25 minutes
Ingredient Substitutions
Chocolate. This cake will be as good as the quality of chocolate used. My top choices in this recipe are Ghirardelli 60% dark chocolate or any other high-quality variety. The darker chocolate used, the richer the cake will taste.
Butter. I always use salted butter in baking, but you can use unsalted as well with great results! To make this cake dairy-free, a vegan butter substitute, like Earth's Balance, can be used.
Granulated sugar. Regular granulated sugar or organic cane sugar both work really well in this flourless chocolate cake recipe.
Sea salt. I recommend using pure, fine sea salt. If you use table salt (iodized salt), you may need to use less.
Store
Store leftovers in an airtight container in the refrigerator for up to 5 days.
Freeze
You can freeze either the whole cake or individual slices. To do this, place the cake or slices on a flat surface (baking sheet) and put them in the freezer to freeze until hardened. Then, wrap them with plastic wrap and put in an airtight container. Freeze for up to 2 months. Thaw gradually in the refrigerator.
